Traveling Wave Amplifier and Relay

In this device, an electron beam emitter 6 supplies a signal to an output transmission line unless the beam is deflected by an incoming signal from the input transmission line.

The structure of both input and output lines includes a flat central conductor 2 surrounded by a flattened helix 3, which in turn is surrounded by an outer sheath
4. Both input and output portions are terminated by suitable impedances 5. The electron beam from the emitter 6 enters the transmission line structure between the helix 3 and the outer sheath 4 through a grid 7 which forms an electrical extension of outer sheath 4. Unless deflected by a signal on the helix 3 of the input line, the electron beam is intercepted by the anode portion of the helix 3 of the output line. Such anode portion, which is indicated at 8, presents an unbroken profile to the beam at the angle of beam presentation. The voltage of emitter 6 (supplied from a source indicated schematically at 9) is chosen to impart a velocity to the electron beam corresponding to the velocity of a traveling wave pulse signal on the input helix.
